variable name - tk

[ee1]

Hi,
suppuse i have some varialbes: foo, bar, aaa.
each varialbe has a value.

and i send to a proc the var name as a string.
how can i get the var value?

for example:
proc {var_name} {

}
i would like to be able to get the value of the variable.
if i send "foo"
i want to see the value of foo ($foo).

i tried: $$var_name, $(var_name), $"$var_name"
but nothing worked...

thanks.

Hi

Use [tt]set[/tt] :

[b]proc[/b] some_proc [teal]{[/teal]var_name[teal]}[/teal] [teal]\[/teal]
[teal]{[/teal]
  [b]global[/b] [navy]$var_name[/navy]
  [b]puts[/b] [green][i]"$var_name's value is [ set $var_name ]"[/i][/green]
[teal]}[/teal]

[b]set[/b] some_var [green][i]"some value"[/i][/green]

some_proc some_var
